BLOWER MOTOR
DESCRIPTION
The blower motor is a 12-volt, Direct Current (DC)
motor with a squirrel cage-type blower wheel that is
secured to the blower motor shaft (Fig. 3). The
blower motor and wheel are located in a housing
near the top of the rear heater-A/C unit in the pas-
senger compartment behind the right rear wheel
house. The rear heater-A/C unit housing must be
removed from the vehicle to access the blower motor
and blower wheel for service. The blower motor and
blower motor wheel are a factory balanced unit and
cannot be adjusted or repaired. If faulty or damaged,
the blower motor and blower wheel must be replaced
as a unit.
